We classified our patients, according to the type and severity of the prevailing dysfunction, into four subsets: Group A—35 subjects with impaired LVSF, all of them having also other associated dysfunctions; Group B—51 subjects with elevated sPAP levels, associated or not with RVD and/or reduced LVEF; Group C—66 patients with DD, but with normal LVF (even if borderline); and Group D—23 individuals with pericardial pathology, frequently associated with other dysfunctions. Here, PDZK1IP1 is linked to dentin dysplasia.
